2020-08-26drm/amdgpu: Fix buffer overflow in INFO ioctlAlex Deucher1-0/+4
The values for "se_num" and "sh_num" come from the user in the ioctl. They can be in the 0-255 range but if they're more than AMDGPU_GFX_MAX_SE (4) or AMDGPU_GFX_MAX_SH_PER_SE (2) then it results in an out of bounds read.

2020-08-15drm/amdgpu: note what type of reset we are usingAlex Deucher5-2/+13
When we reset the GPU, note what type of reset will be used. This makes debugging different reset scenarios more clear as the driver may use different reset methods depending on conditions on the system.
